Naya Rivera Calls Off Wedding With Big Sean After He Admits Cheating

They got engaged after just six months of dating, and now, Naya Rivera and Big Sean are rethinking their fast track to the altar. In fact, the Glee star has put all wedding plans on hold because her rapper beau has admitted to being unfaithful.
Insiders tell Star that after the 26-year-old popped the question in October, his playboy ways did not subside, and he suddenly got cold feet. “It was too much, too fast for him,” a source spills.
Now, Naya’s inner circle is urging her to break things off for good, but the actress refuses to give up so easily. “She’s already picked out a wedding dress and doesn’t want it all to be for nothing,” a pal says. “She’s in denial.”

Naya you might want to save that wedding dress for a more deserving dude.
Update: Ironically the couple who met on Twitter are no longer following each other there any more and there's a shady tweet going around that is supposedly from Naya (we haven't been able to confirm if she actually tweeted and deleted it or if it's doctored) paints a pretty ugly picture of Sean as being shady in all kinds of other ways.

Big Sean has also released a statement.
Hit the flip for that

Looks like Sean is denying the cheating rumors, according to this E! News report:

"After careful thought and much consideration, Sean has made the difficult decision to call the wedding off," a rep for Big Sean said in a statement obtained by E! News. "The recent rumors and accusations reported by so-called or fake sources are simply untrue. Sean wishes Naya nothing but the best and it is still his hope that they can continue to work through their issues privately. We will not be commenting again on this matter."
Last night at the Marie Claire Fresh Faces event in Los Angeles, a subdued-looking Rivera did not appear to be wearing the massive diamond ring that her now ex-fiancé gave her.

Who do you believe?
Here's the photo of Naya from Tuesday night where she showed up sans ring... She posted a smaller version with this caption:
